Cantillon Cuvée du 25eme
Description
It is a classic gueuze bottled in 1990 at the request of a student fraternity - called "Corporatio Brabantia Bruxellensis" - for the 25th anniversary of their existence. The fraternity doesn't seems to be associated with any particular university or school, though they seem to be known for having the biggest codex (called "Florex") in Belgium (2300 pages in both French and Dutch), which is a book containing all the songs and anthems of the group.
